Influence of SiO₂, TiO₂ and Fe₂O₃ nanoparticles on the properties of fly ash blended cement mortars

This study explores the effects of different types of nanoparticles, namely nano-SiO₂ (NS), nano-TiO₂ (NT), and nano-Fe₂O₃ (NF) on the fresh properties, mechanical properties, and microstructure of cement mortar containing fly ash as a supplementary cementitious material. These nanoparticles existed...

Towards understanding the influence of porosity on mechanical and fracture behaviour of quasi-brittle materials: Experiments and modelling

In this work, porosity-property relationships of quasi-brittle materials are explored through a combined experimental and numerical approach. In the experimental part, hemihyrate gypsum plaster powder (CaSO 4 ⋅1/2H 2 O CaSO4⋅1/2H2O) and expanded spherical polystyrene beads (1.5–2.0 mm dia.) have been mixed to form a model material with...
